Are you sure you're not seeing groups that have the same names as users?
On redhat, all new users get a group of the same name created at the same
time ..

Hi all,

When editing a group (user group), the user selection pop-up window 
appears both group and users. Isn't it only users should show up? Why 
both, it is confusing and easy to make mistake with cases that user and

Re: developing with php: the solution

[Sandro D. <san...@ti...>]

  After some hours studying env variables set by apache and miniserv, I
  understood it: miniserv.pl does not set SCRIPT_FILENAME to the complete name
  of the cgi script. It it sufficent to add:

	  $ENV{"SCRIPT_FILENAME"} = $full;

  somewhere aroung line 1300 depending on your webmin release, where all
  environment variables are defined and php will work correctly..., 
  that is to say, it does not issue any "#!/usr/bin/php4" to the browser and 
  phpinfo() works.

  Now we can have a look at web-lib.pl! Should someone know of a module
  developed with this library, please let me know.

have a webmin session which we cannot terminate.  Have used the webmin

Not at all, my trial script -php.cgi-, is as simple as:

    #!/usr/bin/php4 -q
    <?php
    echo "Content-type: text/html\n\n" ;
    echo "Ciao\n";
    ?>

note that the following shell script -sh.cgi-, just works:

    #!/bin/sh
    echo Content-type: text/html
    echo

    echo Ciao

The php scripts works from command line, but from inside webmin returns "No
input file specified"

If you take off the "-q" switch in '#!/usr/bin/php4" php4 will issue a
header (X-Powered-By: PHP/4.1.2 \nContent-type: text/html), the script
executes but the line with '#!...' staff is echoed to the browser...

I think this has really to do with something in the way miniserv.pl deals
with cgi scripts. Since I saw quite a lot of other people asking these
questions on php list, it would be really nice to get an answer from people
that understand how miniserv.pl works.

Thanks in advance. And of course thanks to Jamie for Webmin that makes so
easy to let people administer their boxes...

Whoah!  I had no idea web-lib had been ported to PHP.  I knew there was 
a Python port, though.  I didn't even know PHP could be run standalone 
(I thought it had to have a module in the webserver...shows how much I 
know about PHP).

In that case, it looks like maybe an issue with Webmin not treating it 
as an executable, perhaps?

Have you tested to be sure it runs correctly from the command line?

And have you checked the PHP web-lib routines that you're using to make 
sure they are correct?  It appears to be a 'quick' port...I don't know 
that I would expect it to work perfectly from the get go.

  Is it really needed? I read no mention about it! (nor I understand it!)

  while I managed to use w/ success webmin.py (python library, used only to
  test the example), I was not able to run any example in php.

  I'd like to know if somebody knows of a module written in php, the author
  of web-lib.php (Nicolas Faurant) did not write an e-mail in the file, and
  provided no examples, please, if you read this, let us know...

  Here is the misbehaviour:

     If the php script contains #!/usr/bin/php4, that same string will be
     output to the browser and a warning will be issued:

   Warning: Cannot add header information - headers already sent by (output
   started at /usr/share/webmin/uptimephp/index.cgi:2) in
   /usr/share/webmin/web-lib.php on line 25

     if '-q'(quiet) option is used, no header is issued by php4 and "no input
     specified" appears in the browser.

  I have no problem w/ cgi scripts in bash, tcl, python, awk... what has php
  special? 
  
  Thanks in advance for any reply

Re: developing with php

[Joe C. <jo...@sw...>]

Got three years to spare?  ;-)  (Webmin has been under serious 
development for at least that long...)

To answer your question more seriously:

If you have to ask these kinds of questions, you're not going to have 
the skills needed to reinvent even a small part of Webmin for some time 
to come, regardless of the language used.  A serious PHP /and/ Perl 
hacker with some C skills could probably come up with appropriate glue 
to allow you to write integrated Webmin modules in PHP given enough time 
and inclination.

I'm pretty sure the easier path is simply to learn perl well enough to 
write your module(s) in the language that Webmin currently uses.  You'll 
find Perl to be not much different than PHP, when it comes down to the 
actual gritty bits that do all the work--some things will be easier, 
while other things will be harder.  Depending on your programming 
experience, and enthusiasm, you could potentially be writing reasonably 
good module code in under a month (that's about how long it took me to 
start writing real useful modules--nothing like Jamie's best modules, 
but not entirely ugly, either).

That said, if you really, /really/ must go about it this way, you have a 
couple of choices:

Setup Webmin to run under Apache.  This will allow you to run PHP 
programs alongside Webmin.  You'll then need to teach your PHP modules 
how to deal with ACLs from Webmin, and will also have to have all of the 
normal Webmin files (config.info, module.info, etc.).  This isn't really 
writing a Webmin module in PHP, but it will look roughly like a Webmin 
module, and depending on how clever you are with PHP you can probably 
make it act extremely similar to a Webmin module.

Start with some other similar project that is already written in PHP. 
There are a few out there, I'm sure.  Everybody and his brother who has 
learned a few lines of PHP has had the same thought: "This is easy!  I 
could write a cool program to do ________."  A few of them have probably 
even gotten some working code out there.  So look for something that 
addresses some or all of your needs, and build from there.  You won't 
find anything even approaching Webmin's functionality, but maybe you 
don't need all of the functionality of Webmin for your project.

In all cases, beware of security issues...It is real easy to build 
something that will allow any random user to own your server.

Check the keyfile= line /etc/webmin/miniserv.conf for the path that
webmin is looking for the SSL key at, and copy it from
/space/webmin-1.000/miniserv.pem to wherever the keyfile line points to.

installation problem

[Jannetta S L. <jan...@he...>]

Hi folks

I somehow messed up my upgrade from 0.990 to 1.000 and I now get the
following error at the end of the setup:

Starting Webmin server in /space/webmin-1.000
Failed to open SSL key at /space/webmin-1.000/miniserv.pl line 171.
ERROR: Failed to start web server!

Is there a way of recreating the SSL key, or copying it from it's old
position?

Thanks

Yeah, this is already done .. unfortunately, when the 'null'
beta of redhat 8.0 came out, it was version number 7.3.99.
So I assumed that the next official redhat release would be 7.4 :(

Fortunately this is just cosmetic, and having webmin think you are
